sdd-spec

A delta specification documents only the added, modified, or removed behavior in a system rather than rewriting the entire spec. This Skill automates generating those structured requirements and scenarios for targeted software changes.

To generate structured requirements, delegate execution to the sdd-spec sub-agent. You provide a change proposal and existing specifications, and the Skill reads them to produce new structured scenarios and persisted artifacts.

Modified requirements follow a dedicated workflow that reads the existing specification and preserves all current scenarios. The Skill ensures no original scenarios are lost while injecting the new delta changes into the artifact store.

Yes, technical artifacts are written in English by default, but the Language Domain Contract includes options for Spanish. You can configure the Skill to generate the delta specification artifacts in Spanish.

You need an existing specification and a defined change proposal before automating the delta specification. The Skill requires access to both to read current behavior and generate accurate structured scenarios for the update.

Yes, the execution and persistence contract supports multiple artifact stores. This allows the generated delta specifications and structured requirements to be saved across different storage locations as needed.
